Building Disaster Recovery Serviceguard Solutions Using Metrocluster with EMC SRDF

Limitations of the rolling upgrade for Metrocluster
Following are the limitations of the rolling upgrade for Metrocluster:
• The cluster or package configuration cannot be modified until the rolling upgrade is completed.
If the configuration must be edited, upgrade all the nodes to the new release, and then modify
the configuration file and copy it to all the nodes in the cluster.
• New features of the latest version of Metrocluster cannot be used until all the nodes are
upgraded to the latest version.
• No more than two versions of Metrocluster can be running in the cluster while the rolling
upgrade is in progress.
• The rolling upgrade procedure cannot be used as a means of using multiple versions of
Metrocluster software within the cluster. HP recommends that you upgrade all cluster the nodes
to the latest version immediately.
• HP Serviceguard cannot be deleted on any node when the rolling upgrade is in progress in
the cluster.
